Compression Springs
Silaris provides high-performance Compression Springs as part of our Mechanical Springs product line. These springs are designed to resist axial compressive forces and are widely used in industrial machinery, automotive systems, electronics, and more. They store mechanical energy and return to their original shape after being compressed, offering reliable support and force in dynamic and static applications.
Key Highlights – Compression Springs
Robust construction for repeated compression cycles
Available in various wire diameters, shapes, and materials
Engineered for consistent performance and long-term durability
02.
Extension Springs
Silaris offers durable and precision-engineered Extension Springs designed to absorb and store energy as they are extended. These springs provide a pulling force and are commonly used in applications requiring a return force, such as garage doors, automotive interiors, industrial machinery, medical devices, and agricultural equipment.
Key Highlights – Extension Springs
Designed to resist pulling force and return to original shape
Made from high-tensile wire for superior elasticity
Custom end hooks and loops available for all types of connections
03.
Torsion Springs
Silaris manufactures high-quality Torsion Springs engineered to deliver rotational force or torque. These springs work by twisting their ends along their axis and are commonly used in applications like hinges, levers, garage doors, clothespins, and vehicle suspensions.
Key Highlights – Torsion Springs
Provides torque and rotational energy in mechanical systems
Precision coiled for consistent angular deflection
Engineered for consistent performance and long-term durability
Compact design with high load capacity
Custom stack configurations for tailored load and deflection
Made from stainless steel, alloy steel, and other durable materials
